Description

  • The error "Director Not Reachable" is logged while configuring Director URL in Citrix Probe Agent.
  • The Director URL was accessible via browser from the Probe Agent machine.
  • Probe Agent logs saved at C:\Program Files (x86)\Citrix\Citrix Probe Agent on the probe agent machine shows the below error which does not give much clue.
             ERROR ProbeEndPoint.Log - The parameter is incorrect.
  • Fiddler Traces collected from Probe Agent machine while reproducing the issue shows 401: Unauthorized: Access is denied due to invalid credentials error.

 

Resolution

WORKAROUND

Setup an extra Citrix Director instance without SSON or PIVS that has only Forms authentication enabled for configuring Director Probes.

Helpdesk users/admins can continue to use the existing Director intance with SSON/PIV smart cards enabled for regular access and monitoring,

Problem Cause

  • Windows Authentication was enabled in addition to Forms authentication in Director IIS settings as customer was using PIV smart card authentication.

  • As per current design, with probe Agent Director and StoreFront support the default form-based authentication only. Director does not support Single sign-on (SSO)/PIV smart card authentication with Probe Agent Configuration.
